The Australian, despite the loss, is motivated by the fact that he reached his first ever Masters final.

"Looking back from where I was... I would have never thought I would have had my first Masters 1000 event final," Kyrgios said, as quoted on ATP. "So I'm pretty happy with the result. From where I was to here, it's just been amazing."

Ahead of the US Open, former world number four Cash spoke about his fellow compatriot, claiming that as long as Kyrgios is fresh and fit, he always has a chance of going far in a Grand Slam.

"I have always said Nick will be a danger at the slams but unlikely to get to top one, two or three, as he is an emotional player and that is draining and leads to inconsistent performances,'' Cash told ESPN.

"But he still has the potential to get to a slam semi or final – as long as he is fresh and fit."

The 2017 edition of the US Open gets underway on Monday (28 August), with Kyrgios looking to give a good account of himself in the final Grand Slam of the year.
